By controlling the display means according to the above logical table, both display means are hidden when the spread display means is closed, and both screens are displayed when the display means is opened, and an angle exceeding 200 degrees is displayed. When the display means A is hidden, the display means A is hidden and the display means B is displayed as it is.

[0032] FIG. 10 shows an example of a cross-sectional view of the switch and the switch pressing means of the present invention. In this figure, the switch holding means 47 of FIG. 4 (b) is arranged on the basis of FIG. 7, and FIG. 8 is obtained as an output result, and it is obvious that the display means can be controlled as shown in FIG. Is.

The switch and the switch holding means in FIG . 1 or the constituent means in which the first switch, the second switch, the first switch holding means and the second switch holding means in FIG. 6 are omitted can be implemented. An explanation will be given by taking as an example the display means of the type shown in FIG. 2B, which has not been shown explicitly.

FIG. 13A is a top view of the display device of the type shown in FIG. 2B. Reference numeral 130 is a display unit A, and 131 is the other display unit B of the two-page spread. An electrostatic coupling, pressure-sensitive, or display-integrated type tablet device for detecting the contact position of the pointing object is embedded in each display means or on the surface of each display means, and the surface of the display means is touched with, for example, a finger. By doing so, a contact signal can be sent to the display control means. Reference numeral 132 is a left thumb, and 133 is a right thumb. That is, FIG.
3 (a) is a state in which the display means is held by both hands, and the display device is held by the parents' fingers and the display means is supported by the palm or other fingers.

FIG. 13B is a diagram for explaining the contact area between the finger and the display device when the display device is held with one hand, for example, the right hand, by rotating 130 to make it back-to-back with 131. Reference numeral 134 is a display means A, and 135 is a display means B. Actually, the display means A is bent behind the display means B. Reference numeral 136 is a contact area between the finger that supports the display means A and the display means, and 137 is a contact area between the display means B and the finger that holds the display means B. As shown in this figure, a person usually tries to reduce the area of an indicator that is an obstacle so that the display area of the display means that he or she currently sees is large, and the side of the support to hold the device stably. Increases the display area. The contact area can be easily obtained from the number of contact detection points on the tablet, for example. On the other hand, contact between the display means and the pointing object may occur other than intended, so it is desirable that the contact state be stabilized.

Therefore, both of the spread display means are contacted at the same time, and the contact state becomes steady, for example, the contact state is 3
When it lasts for more than a second, display or non-display of the display unit can be controlled by the difference in contact area between the spread display unit and the pointing object. For the difference in contact area, for example, when one contact area and the other contact area are different from each other by 20% or more, a malfunction can be avoided by performing control.

From the above, for example, when the display device is supported by both hands and both sides are viewed as shown in FIG. 13A, both display means are displayed, and when the display device is held by one hand,
It is possible to perform control such that one side of the display means is displayed and the other side is hidden. It should be noted that the tablet for detecting the contact position may not be present inside or on the surface of the display surface, but may be at a place for holding a display device different from the display surface.

According to the method and principle described above, the display means having a larger contact area between the display means and a pointing object such as a finger is made non-display, so that, for example, when the display device is held by one hand the display means corresponding to the back without you to hide.

FIG. 11 is a diagram showing an example of a cross section of the display device of the type shown in FIG. It is assumed that the display device is as described in claim 1 and claim 2. Reference numeral 110 denotes a coupling portion, which has a structure in which the display surface 117 and the substrate 115 thereof can be rotated 360 degrees about the rotation axis 111. 112
Is a switch holding means attached at a position where the angle between 117 and 116 exceeds 200 degrees. 117 and 115
The combination of 110 and 110 corresponds to the display means A described above. One 116 is the other display surface, and 117 is its substrate. A switch 113 is installed on the substrate, and when the switch 112 comes to the upper surface of 113, the switch receives a pressure and is turned on. A combination of 116 and 114 corresponds to the display means B.

The display means A and the display means B are constituted by, for example, a display-integrated type tablet device, and the contact position can be detected by contacting the surface thereof with an indicator. Reference numerals 118 and 119 represent a state in which the display means A and the display means B are in contact with each other, for example, with a finger. As described above, the contact area between 119 and the display means A is larger than the contact area between 118 and the display means A.

Due to the operation of the switch and the switch holding means described above, the display means A and the display means B are operated when the rotation angle between them exceeds 200 degrees. In claims 1 and 2, the display means of either one (display means A for the sake of simplicity) is hidden by the switch, and the operation of the switch and the contact area between the pointing object and the display means. When the spread display means exceeds a rotation angle of 200 degrees, the display means having a larger contact area between the pointing object and the display means can be limited and hidden by taking the logical product of the differences. Is obvious from the logic table of FIG.

14 (a), 14 (b) and 14
(C) is an example of a diagram for explaining the operation of the page switching means of the present invention. Reference numeral 140 is a display unit A, and 142
Is a display means B. Reference numeral 141 is a page switching means provided on the display means A, and 143 is a page switching means provided on the display means B. Reference numerals 141 and 143 denote triangular areas delimited by the vertical and horizontal midpoints of the display means, which are the home positions of the page-turning fingers when a page of a paperback book or the like is turned with one hand. By touching an indicator, for example, a finger in this area, and moving the finger from left to right while keeping contact with the page switching means, the page can be turned in the forward direction, and the operation of the finger in the backward direction can turn the page in the reverse order. Can be controlled. The moving direction of the contact area can be determined by temporally tracking the vector of the contact area, which is known in the prior art. The page switching means may be the entire area of the display means such as a liquid crystal display integrated tablet, but by limiting to a specific area of the display means as shown in FIG. Malfunctions can be reduced. Further, when the area is limited, it is possible to configure page switching means of the shape of the area, but for example, the entire area is a liquid crystal display integrated tablet, and only the contact in the page switching area is controlled as the page switching operation. It is also possible.

FIG. 14B shows another embodiment of the page switching means, in which the lower quarter area of the display means is used as the page switching means. In FIG. 14 (c), the page switching means is an area in which 20% of the vertical area of the display means and the triangular area of FIG. 14 (a) are combined.

14 (a), 14 (b) and 14
As shown in (c), by arranging the rotation axes of the spread display means symmetrically in the page switching means, right-handed people and left-handed people, right-handed or left-handed pages can be displayed comfortably. Can be turned.

The display device of the present invention is designed on the basis of displaying and viewing information on both of the display means having two facing pages. This is realized by preparing a page buffer memory required for a display page in the page control means or the display means, and successively fetching data corresponding to the display page from the information storage means into the page buffer in accordance with an instruction from the page switching means. For example, a page buffer for two pages is prepared, and when the page switching instruction signal is generated from the page switching means, data for filling two pages of data into the page buffer is fetched from the information storage means into the page buffer. It is possible to display the information on both sides of the spread by managing the fetch management pointer or by managing the page buffer for one page and reading the information twice . If one of the Viewing means is dismissed, capture a control signal to hide one of the display means, the number of times or taking the amount of information taken into the page buffer to one page to the number of one page commensurate By reducing the number, page switching can be controlled.

[0046] Using the Display apparatus are folded and displayed high interest in for example the page was reading current when using information, it is possible to solve the problem in the case where the page is under the control of hidden . This captures a signal for hiding one of the display means, compresses the contents of the display buffer for two pages that have been displayed up to now into one page, and the compressed data is stored in the display buffer of the display page. It can be realized by rewriting the contents. As a page compression method, a conventional technique can be used. For example, when the display information is only text information, the size of the character font is reduced, and in the case of image data, the data can be thinned out.

It should be noted that the display of two pages on one side is limited to only two pages at the moment when the display means on one side is turned off, and the pages before and after may be controlled to be returned to the normal one page display. It is also possible to control so as to reduce and display the two pages as they are, by managing the pointer for managing the data acquisition that is acquired in the page buffer.
